REENFORCEMENT FOR SIDE FRAMES OF CAR TRUCKS.

Application filed July 2, 1925.

This invention relates broadly to side frames for car trucks, and more particularly to a reenforcement for the arch bars of such frames.

The primary objectof the invention is to provide, in association with a railway truck frame of the so-called diamond side type, a simple, effective and readily applicable form of reenforcement for the arch bars of said frame. A

A further object is to provide a reenforcing device or structure of the character mentioned which shall function not only to minimize the tendency of the arch bars to break under stresses imposed theron, but also to so confine and support those portions of the arch bars located at and adjacent to the points at which breakage thereof most frequently occurs that, in the event of breakage at any of said points, displacement of the sundered parts is eectively prevented, thus materially to reduce the liability to accident which is incident to such displacement.

A still further object is to provide a dei vice of the character mentioned having therein openings affording opportunity for inspection of those portions of the arch bars most susceptible to fracture in use.

l IYith these and other important objects in view, the invention consists in the features of construction, combinations of elements, and arrangement of parts which will hereinafter be fully described, reference being had to the accompanying` drawings, in which- Figure 1 is a side elevation of a car truck, illustrating the application of my invention, portions of the truck being shown in dotted linesl Figure 2 is a section on line 2-2,Fig. 1;

Figure 3 is an enlarged perspective view of the main brace or support;

Figures 4 and 5 are similar viewsl of the outer and inner side, or housing, members for ysaid support;

Figure 6 is a similar view of the tension bar rest; and- Figures 7 and 8 are, respectively, views in side elevation and on a reduced scale of modified forms of housing members or faceplates.

Referring to said drawings, 1 indicates the top arch bar, 2 the bottom arch bar and 3 the tie bar of a railway-truck side frame of ordinary diamond-side type.

As a preliminary to describing the invenseria1 No, 41,083.

tion in detail, it is here explained that the posed load, and that said bars in performi ing their intended function, are necessarily at all times subjected to shocks and carrying strains which are more or less severe according to the weight of the load supported thereby, the conditions of operation and handling of the cars embodying them, and the conditions of the trackway and roadbed over which said cars travel. These strains result in frequent fracture and breakage of said bars, Awhich most frequently occur at or adjacent to the angles or curves a and b formed between the horizontal and inclined portions of said bars 1 and 2, which angles or. curves are closely adjacent to the bolster columns of the usual railway truck.

. Interposed between the archV bars 1 and 2 in closely seated relation to the parts usually occupied by the two bolster columns, is an upright post-like supporting member 7 provided in the form of a heavy casting. Said member 7 has head and base portions 7a and 7b at its opposite ends made of suftioiently greater thickness in the direction of the lengths of the arch bars that they will rest upon said bars throughout the eX- tent of the curves a and b of the latter, said portions having their outer surfaces correspondingly curved to seat conformably upon said bars. Said support 7 is rigidly secured in place by means of a rod or bolt 8 directed vertically through the. arch bars 1 and 2 and through a hole 9 provided for said bolt in said support. The lower end or base portion of the support 7 is bifurcated, as shown at 10, to permit inspection through the bifurcation of the upper surfaceof the bottom arch bar 2, as for detection of fractures.

Housing members or face plates 11 and 12 are mounted on the outer and inner sides or faces of the support 7, the same being designed as supports for resisting fleXure of the arch bars in outward, or curve-straightening, directions. Securing said face plates 11 and 12 in place are bolts 13 and 14, of which the former is directed through holes 15, 16 and 17 provided therefor in the inner plate 12, the support 7 and the outer plate 11, respectively, and the bolt 14 is directed through other holes 18, 19 and 2O provided in said members. The plates l1 and 12 have upper end flanges 1la and 12a, respectively, which seat in overlying relation to the adjacent edge portions of the top -face of the top arch bar, and have lower end 'flanges li" and l2", respectively, which closely underlie the bottom arch bar 2 at the curve of the latter, being introduced between said arch bar and the tie bar 3.

Said tace plates ll and l2 have formed on their outer faces adjacent to the lower rear edges thereot angularly disposed lugs 2l and 22, respectively, through which at tachment to lugs on the spring plank 23 is effected, as by means of small bolts 2d.

The inner face plate l2 has an integral angularly disposed bracket 25 formed thereon, and carried by this bracket are lugs 2G adapted for having mounted thereon brake-beam hangers (not shown).

Provided in the face plate 1l adjacent to its upper and lower ends are oblong openings 27 and 2S designed to permit inspection ot the outer edge portions of the arch bars l and 2, respectively, .t and adjacent to the curves a and ZJ.

The inner edge of the outer plate ll is preferably provided with a shallow vrecess 29 affording clearance for the bolster 6 and terminating at its lower end in an upwardly facing shoulder 30 located at a suitable elevation, said shoulder being adapted to serve as a rest for said bolster in case the supporting springs 8l for the latter should become displaced.

l prefer to employ in association with the reenl'orcing structure hereinbefore described a rest for the outer end ot' the bottom arch bar, or tension bar 2, having substantially the form shown in Figs. l and 6, which consists of a fiat horizontal bar portion 32 and a brace portion 33, the former being adapted to be interposed between the top of the journal bof; 5 and the overlying horizontal end portion of said bar 2. The brace portion 38, which is shaped to conformably fit over the edge of the journal box and to seat against the adjacent side of the latter, has its upper surface shaped to closely underlie the bar 2 at and adjacent to the curve or bend formed in the bar between the outer end portion and the inclined portion of the latter, as shown in F ig. l. Obviously, said angular rest constitutes a` supporting brace for the bar 2 at and adjacent to the outermost bend of the latter.

rllhe modified form of housing shown in Fig. 7 consists of a single casting or forging which embodies two face plates 11 connected at their lower ends by a horizontal member formed integral therewith, said tace plates being designed for mounting at opposite sides ot the position occupied by the bolster.

The modified form of face plate shown in F ig. 8 illustrates a. tace plate made in two sections 11 which are relatively adjustable to vary the length thereo'll to suit frames in which the distances between the arch bars l Y and 2 vary from the usual standard.
